Cells are the basic building blocks of all living things. All cells are small 'sacks' composed mostly of water. There are millions of different types of cells, but they are divided into two main groups. The first group, Prokaryotes, is made up of very small cells that have no membrane around their ...

The research of stem cell biology has introduced possibilities of cellular replacement strategies, which, if successful, could create effective treatments for diseases such as Parkinson\'s Disease and Diabetes (type 1), as well as repairs to severe spinal cord injuries that were previously untreatab...

The idea of a perfect race was first thought of way back during World War II, by Adolf Hitler. He wanted a nation of tall, healthy, intelligent, blonde-haired humans and these were the beginnings of biological engineering. The experiments carried out on the Jews, in the concentration camps, were utt...

LIFE The greater mankind's knowledge becomes, the harder it is to define the idea of life. This difficulty is curious since almost all human beings fell that they know, without any ambiguity, the difference between something alive and something dead. However, our advancing knowledge tells ...

Introduction Integrins are a large family of homologous transmembrane linker proteins that include collagen, fibronectin and laminin. They are a family of cell-surface proteins that mediated cell adhesion, a process that is essential for anchorage, and act as cues for cell migration and signals fo...

Secrets of a Salty Survivor The Dead Sea is known for its high salt concentration which inhibits life for most organisms. The high salt concentration damages the organism's DNA by depriving the cell from the water they need to keep the structure of its double helix, leading to a faulty DNA s...

Recently, we have all seen the controversy over whether or not we should attempt to clone. If you haven\'t heard: A group of scientists in Scotland announced the birth of a sheep cloned from embryonic cells, presaging Dolly. Dolly\'s was the birth heard round the world. The first mammal ever cloned...

The article highlights the innuendos of President Bush\'s role in the lack of funding for stem cell research and the stiff limitations the field is plagued with. Whether or not you agree with all of the practices of stem cell research, the article is very informative of its uses. It outlines the ind...

Antoni van Leeuwenhoek Antoni van Leeuwenhoek (layu-wen-hook) was born in Delft, a city in the western Netherlands, on October 24, 1632. His father was a basket-maker, while his mother's family were brewers. Antoni was educated as a child in a school in the town of Warmond. In 1676 he serv...

Living things make up the world as we know it. Living things are involved in our life constantly, seeing that we are alive. There are five characteristics that are common to all living things. Living things are made up of one or more cells. Each cell is made up of living matter and is separate...

Should Embryo Stem Cell Research Be Banned? This is one of the most controversial questions posed in the last century. The issue is simple. Should the federal government fund embryo stem cell research? The answer is extremely complex. At the heart of this controversy, is whether or not, i...

Summary In America, scientific research and technology are advancing every day. Scientists themselves have to read daily to learn the discoveries that have been revealed across the country. These new advances might be the missing link needed to find the cure for a major disease. For medical research...

This paper reports studies and findings of the intercellular adhesion molecule in relationship to the common cold virus and rheumatic diseases. The role of the cell and intercellular adhesion molecules is also examined. Cell-cell adhesion is required at all stages of development and is of importance...

Human cloning in its simplest form is the artificial process of making a genetic copy of a human being. It is the extraction of one organisms DNA being replicated and grown to be an exact copy of the original. This could mean that at some point in the future, any person could have an identical twin ...

At the Roslin Institute in Edinburgh, Scotland, Dr. Keith Campbell, director of embryology at PPL therapeutics in Roslin, and his colleague Dr. Ian Wilmut worked together on a project to clone a sheep, Dolly, from adult cells. On February 22, 1997, they finally succeeded. Dolly was the only lamb bor...

Cloning In the movie Jurassic Park, we watched as man was able to recreate the existence of dinosaurs using blood and DNA preserved many years ago. This process of taking cells and using it to recreate a lifeform is called cloning. A few year ago man was blest with the discovery of cloning. But with...

ENCYCLOPÆDIA BRITANNICA reproduction process by which organisms replicate themselves. In a general sense reproduction is one of the most important concepts in biology: it means making a copy, a likeness, and thereby providing for the continued existence of species. Although...

Since the death of former President Ronald Regan, federal funding of embryonic stem cell research is a topic which continues to be present in our headlines. Some people feel that embryonic stem cells could produce a cure for the devastating disease of Alzheimer\'s. Nancy Reagan is now trying to infl...

Have you ever come across someone suffering from Alzheimer\'s disease? What about Parkinson\'s disease? How about someone terminally ill with liver cancer who is unable to get a transplant? What if a potential breakthrough could solve these problems, but it is surrounded by controversy? One such br...

Normally, when a baby is born approximately nine months after being conceived, he or she has all the features of its parents. It is fully developed for life separate from its mother's umbilical cord. It is fascinating how they are formed inside the womb. Beginning from day one, life has started. Em...

In the 1940's the attention of geneticists was surprisingly focused on the Escherichia coli, colon bacterium. E. coli offered many advantages such as genetically being simpler, they are easily broken open and bacterial cells have little internal structure. For the fact that the E. coli populations...

Cloning Is cloning ethical? the majority of the world would say no but the medical research possibilities associated with it are endless. In 1997 when Dolly the lamb was born we began to think, wow if it's possible to clone an animal, why not a human in the future? It soon became known that it was p...

Before giving this assignment to work on I was 100 percent against stem cells research. But due to extension research I found out that stem cells can provide us with a myriad of possibilities in medical technology, but not without bringing with it serious moral and ethical dilemmas. For the s...
